World’s Tiniest Chameleons Found in Madagascar

Researchers have recently discovered four new chameleon species, which rank among the world’s tiniest reptiles. Adults of the smallest species are just over an inch from snout to tail.

The four new species belong to the genus Brookesia, also known as the leaf chameleons, which live in remote rainforests in northern Madagascar. The genus is already known to contain some very small species, with members typically resembling juvenile versions of larger species.

Brookesia species tend to live within a very small range. Half the members of this genus are found in only a single location and the smallest of the newly found species — Brookesia micra — lives only on a small island called Nosy Hara. Extreme miniaturization of this sort is common in island populations. Known as island dwarfism, it may occur due to limited resources and pressure to reproduce faster.

'Supergiant' amphipod discovered in deep sea near New Zealand

Scientists on an expedition to sample a deep-sea trench got a surprise when their traps brought back seven giant crustaceans glimpsed only a handful of times in human history.

The "supergiant" amphipods are more than 20 times larger than their typical crustacean relatives, which are generally less than a half-inch long, and thrive in lakes and oceans around the world. They are sometimes called the "insects of the sea."

The largest of the seven specimens was about 11 inches long.

The pale, leggy creatures were found 4 miles down in the Kermadec Trench, off the northeast coast of New Zealand, one of the deepest trenches on Earth.

In addition to the animals captured in the trap, a seafloor camera more than a mile away spied at least nine supergiant amphipods. It's not clear why so many of the typically elusive creatures were in the area. A week later, when the expedition returned to the same spot, there was no sign of the supergiant amphipods.

Supergiant amphipods (Alicella gigantea) were first discovered in 1899, when a trawling expedition turned up two specimens from the Atlantic Ocean. The species wasn't seen again for nearly 100 years. In the 1970s, scientists photographed the oversized creatures in the northern Pacific Ocean, hundreds of miles north of Hawaii.

Den Camera Shows Baby Bears’ Birth

Thanks to fiber-optic camera technology, you can watch real-time footage of a black bear named Lugnut as she hibernates in a den beneath an upturned sugar maple in northern Maine. 

Just two weeks ago, the 8-year-old Lugnut gave birth to two cubs (watch video above.) Because of their demands, her hibernation won’t be as deep as usual, and she’ll wake regularly to check on them. Most of the time, however, the cubs will be curled up against Lugnut’s warm belly, nursing as she sleeps.

The cubs will likely stay in the den for several months, and with their mother for more than a year, departing only when they’ve learned enough to survive on their own. The camera is expected to stay on indefinitely, so viewers will have a chance to watch them grow up.
